Answer: 1970s

Explanation: The prevailing model for planetary acceleration also known as the fractal assembly dating back to 18th century assumes that the solar system is made up of small grains striking each other chaotically into bigger ones, to form planetesimals.

Plastesimals then collide to form planets. This model was proposed  by Russian astronomer Victor Safronov  and it was further translated in English in 1970s by George Wetherill.

This remained same for almost next 40 years.

Allen has been studying the genetic material of dogs, to get more insight
kati45 [8]

Answer:

Nucleic Acids

Explanation:

Nucleic acids are DNA and RNA and they are the molecules responsible for containing the genetic material of all living beings. Thus, DNA and RNA are the molecules responsible for establishing the variability and different characteristics between dog breeds, through the genetic information that each of them houses.

In this case, among the options given in the question above, we can confirm that if Allen has studied the genetic material of dogs to better understand why there are so many different breeds, he must have studied nucleic acids.

Which organic molecule is correctly paired with an end product of its break down via hydrolysis?
Gnoma [55]

Answer:

protein - amino acid

Explanation:

Proteins are one of the four major biomolecules in nature. Proteins are polymers of monomeric units called AMINO ACIDS. Amino acids are joined together by a type of covalent bond called PEPTIDE BOND to form proteins. Hence, since proteins are made up of amino acids, the hydrolysis of proteins will result in amino acids.

Hydrolysis is the breaking down of a large polymer into its monomeric unit with the release of water (H2O) molecule as a product. The bonds that forms between the respective amino acids are broken, hence, releasing the amino acids.
